Nyquist acoustic insulation systems are professional acoustic devices designed for precise sound field control and elimination of unwanted reverberation in demanding commercial interiors. Our solutions are based on hard engineering data, which effectively reduces RT60 time and significantly increases speech intelligibility index (STI) in class A offices, hotels, and educational facilities. Each absorber and sound barrier in our offer meets rigorous PN-EN standards and has the necessary fire safety certificates, ensuring full fire safety and compliance with building law regulations. For architects and investors, choosing Nyquist systems guarantees a high ROI and support in the BREEAM, LEED, and WELL certification process. We use eco-friendly PET felt and proprietary technologies such as EcoBoard, which combine rigorous sound physics with the aesthetics of biophilic design, eliminating the risk of costly acoustic corrections after project completion. We design solutions that translate into real work comfort and measurable acoustic safety, providing space users with optimal conditions for concentration and confidentiality of conversations without compromising industrial design.
